These are sandals made of mesh material for excellent breathability, with adjustable straps. I am giving them away because my child outgrew them. There are about two holes near the toes on the insole, but they can still be worn for activities like playing in the river. The soles are worn down, but they should be sufficient as long as you are not on rocky or sharp terrain. They are easier to put on and take off than water shoes that are like socks. These will be shipped by crushing them to fit into a Yu-Packet Post package. Thank you for your understanding.
